Description

Fixing base, lamp fixing device and lamp

Technical Field

The application relates to the field of lamps, in particular to a fixing seat, a lamp fixing device and a lamp.

Background

The lamp is an electrical appliance essential to daily life of people. The traditional lamp is usually fixed on a foundation through different installation chassis, and lamps of different manufacturers and different models have different structures and sizes of the installation chassis, so that during installation, corresponding holes are drilled on the foundation according to the respective structures of the installation chassis, the installation and the fixation are carried out through bolts, expansion screws and the like, and the connection is carried out separately. When a new lamp needs to be replaced, the mounting chassis and the wiring are often replaced again, and the mounting mode is very complicated.

In order to simplify the maintenance and replacement difficulty of the lamp, lamps with a uniform lamp fixing device are continuously available in the current market, the lamp fixing device in the lamp is generally divided into two parts, one part is used for fixing on a foundation and can be called as a fixing seat, and the other part is fixedly connected with a lamp body and can be called as a connecting seat.

After the fixing seat is fixed on the basis, the fixing seat can be quickly, simply and conveniently mechanically fixed and electrically connected with the connecting seat, so that the installation process of the lamp is greatly simplified. Especially when changing lamps and lanterns, because every kind of lamp body all has the same connecting seat, consequently can directly change the lamp body and needn't dismantle the fixing base again, simplified the change process by a wide margin.

The fixing base of the related art generally includes a main body for mechanically fixing and receiving the terminal box, and a terminal box for electrically connecting, so that a power source needs to be introduced into the terminal box when the fixing base is installed. However, the space inside the main body is narrow, which is inconvenient to operate, and the main body and the junction box are usually connected and fixed by a fixed connection or a complex structural connection method (for example, by a plurality of screws), which makes the wiring very difficult.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 schematically shows the structure of a holder 1000 according to an embodiment of the application in a top view. Fig. 2 is an exploded schematic view of fig. 1. Fig. 7 schematically shows a perspective view of the first body portion 1. As shown in fig. 1, 2 and 7, the fixing base 1000 includes a first main body 1 and a junction box 200 detachably mounted in the first main body 1.

Specifically, the first body portion 1 includes a bottom end plate 100 and a side wall 104. In one embodiment, the sidewalls 104 are circumferentially distributed vertical sidewalls. The bottom end plate 100 and the side wall 104 enclose a containing cavity 101, and the surface of the bottom end plate 100 enclosing the containing cavity 101 is a bottom end surface 100A. The receiving cavity 101 is substantially basin-shaped as a whole. Of course, the bottom end plate 100 can have other shapes as long as it forms the receiving cavity 101 together with the side wall 104, which will not be described herein. Meanwhile, a first detachable connection portion for directly detachably connecting with a junction box is further provided on the first main body portion 1, which will be described in detail below.

The junction box 200 has a first electrical connection 2021. Meanwhile, a second detachable connecting portion for detachably engaging with the first detachable connecting portion is further provided on the junction box 200, and the first detachable connecting portion and the second detachable connecting portion are configured to be detachably connected by relatively rotating along a rotating axis, and the junction box 200 can be detachably fixed in the accommodating chamber 101 by the detachable connection. In order to reduce the overall thickness of the fixing base 1000, the junction box 200 is usually attached to the bottom end plate 100, and therefore the rotation axis is preferably perpendicular to the bottom end plate 100.

After the terminal box 200 in this embodiment is fixed in the accommodating cavity 101, the first electrical connection portion 2021 may face the opening of the accommodating cavity 101 or depart from the opening of the accommodating cavity 101, and when the first electrical connection portion 2021 departs from the opening of the accommodating cavity 101, a mounting through hole 102 communicating with the accommodating cavity 101 may be provided on the bottom end plate 100 for exposing the first electrical connection portion 2021 to the outside. In this embodiment, the first detachable connecting portion and the second detachable connecting portion may adopt a plurality of different matching structures, which will be described below by way of example.

When the mounting through hole 102 is provided on the bottom end plate 100, the second connection portion 202 may be provided on the junction box 200 to be detachably mounted at the mounting through hole 102, and the first electrical connection portion 2021 is outside the accommodation chamber 101 through the mounting through hole 102 (as shown in fig. 7). Thus, the junction box 200 is detachably mounted in the first body 1.

As shown in fig. 2, 3 and 8, the mounting through-hole 102 is circular, and the cross-sectional shape of the second connection portion 202 is also circular, and the diameters of the two match. Thus, after the terminal block 200 is mounted at the mounting through hole 102, the orientation of the terminal block 200 is rotatably adjusted, thereby further facilitating the user to perform the wiring operation. It is to be understood that the diameter of the second connection portion 202 and the diameter of the mounting through-hole 102 may be determined by a tolerance fit principle so that the second connection portion 202 can be smoothly mounted into the mounting through-hole 102.

In particular, the second detachable connection may be configured with a radially outwardly extending extension 205 on a circumferential outer side of the second connection 202, at least two indentations 206 being configured on the extension 205. While the first detachable connection may be designed as a claw 105 configured around the mounting through hole 102, the claw 105 matches with the notch 206, and a catching gap may be formed between the claw 105 and the bottom end face 100A. The extension 205 enters the clamping gap through the notch 206, and then the notch 206 and the claw are staggered by relative rotation along the rotation axis, so that the extension 205 can be clamped with the claw 105. Thus, when assembled, aligning the notch 206 on the extension 205 with the pawl 105, the extension 205 will be positioned around the mounting through-hole 102 and the second coupling portion 202 will be aligned with the mounting through-hole 102; the second coupling portion 202 (or the terminal block 200) is then rotated so that the claws 105 are offset from the notches 206 and snap into engagement with the extensions 205, as shown in fig. 9. The rotating clamping assembly mode is very simple, and a user can rapidly complete the assembly of the first main body part 1. Preferably, a plurality of claws 105, for example two claws 105, may be arranged in the circumferential direction, wherein in the radial direction the two claws 105 are arranged diametrically opposite each other and the two indentations 206 are correspondingly arranged diametrically opposite each other, which may simplify the design of the indentations 206 and the claws 105.

Preferably, as shown in fig. 3, the extension 205 includes a beveled guide region 207 and a fastening region 208. The ramped guide area 207 is adjacent the notch 206, the fastening area 208 is in smooth engagement with the ramped guide area 207, and the fastening area 208 is capable of secure engagement with the pawl 105. Thus, under the guidance of the inclined guide region 207, the second connecting portion 202 can be rotated more smoothly and the fastening region 208 can be snapped with the claws 105, so that the terminal block 200 can be assembled with the first body portion 1 more smoothly.

More preferably, an abutting surface can be formed on the terminal block 200, such as a side surface of the extension portion 205 facing the bottom end surface 100A, and the abutting surface abuts against the bottom end surface 100A when the inclined surface guiding area 207 is located in the clamping gap, and a side of the fastening area 208 facing away from the bottom end surface 100A is flush with a side of the claw 105 facing the bottom end surface 100A or is further away from the bottom end surface 100A. This allows the jaws 105 to be tightly and clampingly engaged with the fastening areas 208 by merely rotating the terminal block 200, thereby further simplifying the assembly process. Still more preferably, as also shown in FIG. 3, the ramped guide area 207 is only on one side of the notch 206. Thus, the terminal block 200 can be engaged with the bottom end plate 100 only by rotating it in one direction, while rotating the terminal block 200 in the opposite direction can separate it from the bottom end plate 100, which is a foolproof structure for the case of requiring a specific orientation of the lead part 201, further facilitating the assembly of the first body part 1.

Thus, when the user performs the wire connection operation, the terminal block 200 is first detached from the mounting through hole 102. After the cable is connected to the junction box 200, the junction box 200 is mounted in the mounting through-hole 102. Thus, the wiring operation is not restricted by the accommodation chamber 101 of the first body portion 1, and the wiring operation is greatly facilitated. In addition, the rest space of the accommodating cavity 101 can be used as a wire hiding space so as to hide redundant cables in the accommodating cavity 101. In one embodiment, the ratio of the length of the junction box 200 to the radius of the bottom end plate 100 is less than or equal to 1:2 in the radial direction. Thus, the space for the wire connection operation is large, so that the user can conveniently complete the wire connection operation.

As shown in fig. 2, a baffle 106 is provided between the adjacent claws 105, and the extension 205 of the junction box 200 abuts against the baffle 106. The stop plate 106 can block the extension 205 from disengaging from the pawl 105, thereby improving assembly stability. In addition, for the case where a specific direction of the lead part 201 is required, the baffle 106 also serves as an aid in determining the direction of the lead part 201, further facilitating the assembly of the first body portion 1. In a preferred embodiment, the baffle 106 is arcuate and conforms to the circumferential extent of the mounting through-hole 102.

Fig. 4 schematically shows another way of assembling the terminal block 200 with the first body portion 1. As shown in fig. 4, an internal thread 1020 is formed on the mounting through hole 102, and an external thread 2020 matching the internal thread 1021 is formed on the circumferential outer wall of the second connection portion 202. Thus, the second connection portion 202 is screwed to the mounting through hole 102, that is, the terminal block 200 is screwed to the first body portion 1, and the orientation of the terminal block 200 is rotatably adjusted.

In this embodiment, the axis of the mounting through hole 102 and the rotation axis of the terminal block 200 may be coaxially arranged, so that the terminal block 200 may not be eccentrically displaced with respect to the mounting through hole 102 when rotating, and may maintain its position.

For the solution without the installation through hole 102 on the bottom end plate 100, the above mentioned matching structure of the claw 105 and the extension portion 205 or the matching structure of the internal thread 1020 and the external thread 2020 can still be adopted, and these structures need not be arranged around the installation through hole 102, and the arrangement position of the first electrical connection portion 2021 in this solution is generally opposite to the above solution, that is, the first electrical connection portion 2021 is located on the side of the terminal box 200 away from the bottom end face 100A.

As also shown in fig. 3, the terminal block 200 further includes a lead portion 201, and the lead portion 201 is located in the accommodating cavity 101 of the first body portion 1. The lead wire portion 201 is used to connect with a cable. The second connecting portion 202 is removably mounted at the mounting through hole 102, preferably in a detent assembly after rotation, and can be disengaged after reverse rotation. Since the first electrical connection portion 2021 and the second connection portion 202 are integrally formed, the first electrical connection portion 2021 can be ensured to be located outside the bottom end plate 100 through the mounting through hole 102 only by mounting the second connection portion 202 in place during assembly. This facilitates the process of assembling the first main body portion 1 without paying particular attention to the assembled state of the first electrical connection portion 2021.

Fig. 5 and 6 show an internal structure of the junction box 200, and as shown in fig. 5 and 6, the junction box 200 includes a box cover 250 fastened together and a junction module 210 disposed in the box cover 250. The wiring module 210 includes a wiring terminal 211 and an electrode 212 electrically connected to the wiring terminal 211. The connection terminal 211 is in the lead portion 201 and the electrode 212 forms an electrical connection means of the first electrical connection portion 2021. In the use state of the first body part 1, the outside cable is electrically connected to the connection terminal 211 (for example, by at least two cables including live and neutral; in other preferred embodiments, three cables including live, earth and neutral) and the lamp is powered through the connection terminal 211 and the first electrical connection 2021. Since the wiring block 210 is a complete circuit block, only the wires and the connection terminals 211 need to be electrically connected together in the wiring operation, thereby simplifying the wiring operation. In one particular embodiment, the junction module 210 has three terminals 211 and three corresponding electrodes 212. The three connection terminals 211 may be connected to the corresponding three cables, respectively. For example, the three wires are live, ground and neutral, the three terminals 211 are positive, negative and ground, and the three electrodes 212 are positive, negative and ground, respectively. In other embodiments, there are two connection terminals 211 and two corresponding electrodes 212. The two connection terminals 211 may be connected to the corresponding two cables, respectively. For example, the two wires are live and neutral, the two terminals 211 are positive and negative, and the three electrodes 212 are positive and negative, respectively.

Specifically, as shown in fig. 5, the connection module 210 includes a metal spring piece 213, a first end of which is located in the lead portion 201 to form a connection terminal 211, and a second end of which forms an electrode 212 of an electrical connection device as the first electrical connection portion 2021. The wire connecting module 210 further includes an elastic clamping piece 214 under the metal spring piece 213. The elastic clamping piece 214 includes a straight portion 216 mounted on the bottom surface of the terminal block 200 and a bent portion 215 bent toward the metal elastic piece 213 with respect to the straight portion 216. Thereby, the bent portion 215 elastically contacts the first end of the metal elastic piece 213. The junction module 210 also includes a button 217 above the metal dome 213 and extending beyond the top surface of the junction box 200. The presser foot 218 of the button 217 is located in the terminal box 200 and is pressed against the bent portion 215 of the elastic clamp piece 214 across the first end of the metal elastic piece 213. According to this structure, when performing the wire connection operation, first pressing the button 217 to press the bent portion 215 apart from the first end of the metal elastic piece 213 to insert the cable between the bent portion 215 and the metal elastic piece 213; then releasing the button 217 causes the kink portion 215 to spring back and clamp the cable together with the metal dome 213. Thus, the electrical connection of the cable to the wiring module 210 is very conveniently achieved, and no other auxiliary tools are required, simplifying the wiring operation.

The bent portion 215 is further bent in a direction away from the lead portion 201, and a clamping slit 219 is formed in the bent portion 215. The apex of the clamping gap 219 faces the lead portion 201 and the opening faces away from the lead portion 201. Thus, after the electrical connection between the cable and the wiring module 210 is completed, the cable is clamped by the clamping gap 219 and is difficult to be removed from the wiring module 210, thereby improving the electrical connection stability between the cable and the metal elastic sheet 213.

The metal spring piece 213 is configured such that the width of the first end thereof is smaller than the width of the bent portion 215 of the elastic clamping piece 214. The button 217 has two press legs 218, and the two press legs 218 ride over the first end of the metal spring piece 213 and press-contact with the bent portion 215 of the elastic clamp piece 214. According to this structure, the folded portion 215 can be pushed more stably by pressing the button 217, and the cable can be inserted between the two presser feet 218, thereby smoothly completing the electrical engagement of the cable with the metal elastic piece 213.

As also shown in fig. 7, the first electrical connection portion 2021 may be a rotary structure having a rotary shaft as a rotary center. A corresponding number of electrical connection terminals are provided inside the first electrical connection portion 2021 corresponding to the above-mentioned connection terminals 211 and electrodes 212, the electrical connection terminals being coaxially provided from the inside to the outside along the rotation axis. In the present embodiment, the electrical connection terminal can be designed as a receiving slot with electrical connection capability, see fig. 7, including a first receiving slot 41, a second receiving slot 42 and a third receiving slot 43. Specifically, the edge of the second connecting portion 202 of the junction box 200 is provided with a first receiving cavity 1B recessed inward. The inner wall of the first housing chamber 1B is formed with a first cylindrical insulating portion having a predetermined height, a second cylindrical insulating portion having a height equal to or higher than the height of the first insulating portion and being provided in parallel with the first insulating portion, and a third cylindrical insulating portion having a height equal to or higher than the height of the second insulating portion and being provided in parallel with the second insulating portion, an annular first housing groove 41 is formed between the first insulating portion and the second insulating portion, an annular second housing groove 42 is formed between the second insulating portion and the third insulating portion, and a circular third housing groove 43 is provided in the center of the third insulating portion.

Further, as shown in fig. 5, in the preferred embodiment of the present invention, the number of the poles 212 of the junction block 210 of the junction box 200 is three, i.e., the positive pole, the negative pole and the ground level, as described above. The three electrodes are formed by bending metal spring pieces 213. The three electrodes 212 extend into the first receiving groove 41, the second receiving groove 42, and the third receiving groove 43, respectively.

Fig. 10, 11, and 12 schematically illustrate a luminaire mounting arrangement 2000 according to one embodiment of the present application. As shown in fig. 10, 11 and 12, the lamp fixture 2000 includes a fixing base 1000 and a connecting base 2002 used in a mating manner, wherein the main body structure of the first body portion 1 is as described above and is mounted to a base such as a ceiling or a wall in advance, and the connecting base 2002 is matched with the first body portion 1.

The structure of the fixing base 1000 in this embodiment is the same as that in the above embodiment, and is not described herein again. The connecting socket 2002 of the present embodiment has a second main body 2A, the second main body 2A of the connecting socket 2002 is provided with a second receiving cavity 2B for receiving the first main body 1, the inner wall of the second receiving cavity 2B is provided with a second engaging portion, and a second electrical connecting portion 2111 is provided at the center of the second receiving cavity 2B.

When it is required to mount the lamp to a base such as a ceiling or a wall, the operator merely pushes up the connection socket 2002 to make the second receiving cavity 2B of the second body portion 2A of the connection socket 2002 receive the first body portion 1, and then, by only axially rotating the connection socket 2002, the mechanical connection between the first coupling portion of the first body portion 1 and the second coupling portion of the connection socket 2002 and the electrical connection between the first electrical connection portion 2021 and the second electrical connection portion 2111 of the connection socket 2002 can be simultaneously achieved, thereby achieving the mechanical connection and the electrical connection of the lamp. Herein, the term "axial direction" used in the preferred embodiment of the present invention refers to an axial direction of the rotating shaft. The term "push-up" used in the preferred embodiment of the present invention means to push the connection holder 2002 in the axial direction toward the direction close to the first body part 1 or to push the connection holder 2002 in the axial direction toward the direction in which the relative distance between the connection holder 2002 and the first body part 1 is decreased.

When the lamp is disassembled, the operator only needs to push up the connecting seat 2002 first and then rotate the connecting seat 2002 in the opposite direction, and then separate the connecting seat 2002 from the first main body 1, so as to release the mechanical connection between the first combining part of the first main body 1 and the second combining part of the connecting seat 2002 and the electrical connection between the first electrical connection part 2021 of the first main body 1 and the second electrical connection part 2111 of the connecting seat 2002, and then disassemble the lamp. Through the lamp fixing device provided by the preferred embodiment of the invention, an operator can quickly install and detach the lamp, so that the lamp fixing device is simple to use and convenient to maintain.

Preferably, the lamp fixing device 2000 further has an elastic element 2010, and the elastic element 2010 is configured to apply an axial acting force and a radial friction force between the first body portion 1 and the connecting seat 2002 so as to avoid a relative displacement between the assembled connecting seat 2002 and the first body portion 1, i.e. to ensure that the connecting seat 2002 does not move up and down and left and right relative to the first body portion 1 after the installation of the lamp is completed. Further, as shown in fig. 10, the elastic element 2010 may be disposed on the bottom end surface of the first main body portion 1 of the fixing base 1000 at a position close to the first combining portion for applying an axial force to the bottom end surface of the second accommodating cavity when the first combining portion of the fixing base 1000 is connected with the second combining portion of the connecting base 2002. Further, an elastic element 2010 may also be disposed on the bottom end surface of the second receiving cavity of the connecting seat 2002 at a position close to the second combining portion (not shown) for applying an axial acting force and a radial friction force to the bottom end surface of the first main body portion of the fixing seat 1000 when the first combining portion of the fixing seat 1000 is connected with the second combining portion of the connecting seat 2002. Further, the elastic element 2010 may be disposed on both the bottom end surface of the first main body portion of the fixing seat and the bottom end surface of the second receiving cavity of the connecting seat (not shown). Further, the elastic element 2010 is a spring or other metal spring sheet, and preferably, as shown in fig. 11, the elastic element 2010 disposed on the bottom end surface of the first main body portion of the fixing base includes an elastic portion 2011 and a pressing portion 2012, the pressing portion 2012 is fixedly connected with the elastic portion 2011, when the first main body portion 1 is connected with the connecting base 2002, the elastic portion 2011 is pressed by the junction box 200, so that the pressing portion 2012 of the elastic element 2010 presses the cavity bottom end surface of the connecting base 2002 downward, at this time, the elastic portion 2011 is in a pressed state, and an axial acting force is generated between the first main body portion 1 and the connecting base 2002, so as to ensure that the connecting base 2002 does not move up and down and left and right relative to the first main body portion 1 after the lamp is installed. Further, the elastic elements 2010 are uniformly arranged at positions close to the first coupling portion with the center of the bottom end surface 100A of the first body portion 1 as a center or at positions close to the second coupling portion with the center of the bottom end surface of the second receiving cavity 2B of the connecting seat 2002 as a center. Further, the number of the elastic elements 2010 corresponds to the number of the first or second coupling portions, and the elastic elements 2010 and the first and second coupling portions are linearly arranged in a radial direction. Preferably, the number of the elastic elements 2010 is 3.

Preferably, the first combining portion of the first body portion 1 is at least two protrusions 2003 provided along the circumferential direction of the first body portion 1. The second combining portion of the connecting seat 2002 is correspondingly at least two U-shaped mounting grooves 2005 arranged along the circumferential direction of the inner wall of the second accommodating cavity 2B, and the U-shaped mounting grooves 2005 include an opening end 2051 and a limiting structure 2052. When the first body portion 1 is combined with the connecting seat 2002, the protruding block 2003 of the first body portion 1 is inserted from the open end 2051 of the U-shaped mounting groove 2005, and rotates along the circumferential direction of the inner wall of the second receiving cavity 2B until the protruding block 2052 rotates to the position of the limiting structure 2052 of the U-shaped mounting groove 2005, that is, the first combining portion of the first body portion 1 and the second combining portion of the connecting seat 2002 are mechanically connected.

Preferably, as shown in fig. 10, a height difference is formed between the limiting structure 2052 of the U-shaped mounting groove 2005 and the open end 2051, and the limiting structure 2052 is higher than the open end 2051. When the lamp is installed, the connecting seat 2002 is pushed upwards, the axial acting force of the elastic element 2010 on the connecting seat 2002 is overcome, the protruding block 2003 of the connecting seat 2002 is pushed to the position close to the opening end 2051 of the U-shaped installation groove 2005, then the protruding block 2003 enters from the opening end 2051 of the U-shaped installation groove 2005, and the protruding block 2003 rotates along the circumferential direction of the inner wall 2B of the second accommodating cavity until the protruding block abuts against the inner side wall of the limiting structure 2052. Due to the existence of the axial acting force of the elastic element 2010, the connecting seat 2002 axially moves towards the direction away from the first main body part 1 until the top surface of the projection 2003 of the first main body part 1 is attached to the inner top surface of the limiting structure 2052 of the connecting seat 2002, so that the mechanical connection between the first combining part of the first main body part 1 and the second combining part of the connecting seat 2002 is realized. Afterwards, between first main part 1 and connecting seat 2002, because the produced axial effort of elastic element 2010 always exists to and under the effect of lamps and lanterns self gravity, first main part 1 and the mutual block of connecting seat 2002 become more firm, the condition that the lamps and lanterns rocked about can not appear.

Preferably, the number of the second combining parts is in a multiple relation with the number of the first combining parts, and the number of the second combining parts is not less than the number of the first combining parts. Specifically, the number of the first coupling portions, such as the protruding blocks 2003, is preferably 3, the number of the second coupling portions, such as the U-shaped mounting grooves 2005, is 6, the 3 protruding blocks 2003 are spaced at the same angle, and the 6U-shaped mounting grooves 2005 are spaced at the same angle, so that the mechanical connection between the first coupling portion of the first main body portion 1 and the second coupling portion of the connecting seat 2002 can be realized only by a small-angle rotation, and the lamp can be mounted and dismounted more quickly.

Preferably, the U-shaped mounting groove 2005 further has a triangular guide portion 2053 for guiding when connection is made between the projection 2003 of the first body portion 1 and the U-shaped mounting groove 2005 of the connection holder 2002. Specifically, the top end of the guide part 2053 faces the bottom end surface of the first main body part 1, and the two sides of the guide part 2053 are small inclined surfaces, so that an operator can quickly and accurately place the bump 2003 at the opening end 2051 of the U-shaped mounting groove 2005 under the guiding action of the small inclined surfaces, and therefore the alignment mounting is performed without clearly observing the relative position of the bump 2003 and the U-shaped mounting groove 2005, and the blind mounting of the lamp can be realized only by hand feeling.

Preferably, the U-shaped mounting groove 2005 further has a hooking portion 2054, the hooking portion 2054 being a small slope extending toward the bottom end surface of the second receiving cavity 2B adjacent to the opening end 2051 of the U-shaped mounting groove 2005. By arranging the hooking part 2054, an operator needs to push up and then rotate the connecting seat 2002 to detach the lamp when detaching the lamp. Specifically, when it is necessary to separate the first body part 1 and the connection holder 2002, the operator cannot directly separate the first body part 1 and the connection holder 2002 by reversely rotating the connection holder 2002 because the hooking part 2054 blocks the projection 2003 from being directly removed from the U-shaped mounting groove 2005 due to the presence of the hooking part 2054. At this time, an operator needs to push up the connecting seat 2002 first, because the positions of the first body portion 1 and the protruding block 2003 are fixed, the upward movement of the connecting seat 2002 causes the top surface of the protruding block 2003, which is originally attached to each other, to be separated from the inner top surface of the limiting structure 2052 of the U-shaped mounting groove 2005, the opening end 2051 of the U-shaped mounting groove 2005 correspondingly moves to a position with the same height as the protruding block 2003, and then the connecting seat 2002 is rotated reversely, so that the lamp can be detached. The configuration that the lamp can be detached by pushing up and then rotating the connecting seat 2002 reduces the possibility that an operator detaches the lamp due to misoperation, reduces the possibility that a child detaches the lamp privately to cause danger, and improves the connection stability between the first body portion 1 and the connecting seat 2002 and the electricity utilization safety of the lamp.

In this embodiment, the second electrical connection portion 2111 of the connection seat 2002 includes the same number of conductive terminals as the receiving slots on the first electrical connection portion 2021 from the inside to the outside along the rotation axis, and the positions of the conductive terminals and the receiving slots are in one-to-one correspondence. When the first electrical connection portion 2021 is mated with the second electrical connection portion 2111, the conductive terminals can extend into the corresponding receiving slots to achieve electrical connection. Preferably, as shown in fig. 10 and 12, the second electrical connection portion 2111 of the connection socket 2002 includes a first conductive terminal 2061, a second conductive terminal 2062 and a third conductive terminal 2063 which are sequentially distributed from the outside to the inside. When the first combining portion of the first body portion 1 is connected to the second combining portion of the connecting seat 2002, the first conductive terminal 2061, the second conductive terminal 2062, and the third conductive terminal 2063 are respectively received in the first receiving groove 41, the second receiving groove 42, and the third receiving groove 43 and electrically connected to the electrodes in the receiving grooves, so as to realize the electrical connection between the first electrical connection portion 2021 of the junction box 200 and the second electrical connection portion 2111 of the connecting seat 2002. Further, the first conductive terminal 2061 and the second conductive terminal 2062 are metal rings respectively adapted to the size and shape of the first receiving groove 41 and the second receiving groove 42, and the third conductive terminal 2063 is a metal pin adapted to the size and shape of the third receiving groove 43. By the arrangement of the annular electrical connection, the contact areas between the first, second and third receiving

grooves

41, 42 and 43 and the first, second and third

conductive terminals

2061, 2062 and 2063 are increased, so that the first electrical connection portion 2021 and the second electrical connection portion 2111 can be electrically connected in any relative rotation positioning direction, and the first, second and third insulating portions insulate the first, second and third

conductive terminals

2061, 2062 and 2063 at intervals, thereby improving the safety of electricity utilization.

Preferably, as shown in fig. 10, the first body portion 1 is formed with a mounting seat 2007 formed to protrude outward from an upper end edge thereof, and the first body portion 1 is connected to a ceiling or a base such as a ceiling through the mounting seat 2007. Specifically, the mounting bracket 2007 is provided with a plurality of screw holes for screwing with a ceiling or a ceiling.

Preferably, as shown in fig. 12, the second body portion 2A of the connecting socket 2002 is formed with an annular bearing portion 2008 formed to protrude outward from an upper end edge thereof, and the lamp is connected to the connecting socket 2002 through the annular bearing portion 2008.

As shown in fig. 17, in the luminaire 1700 including the luminaire fixture 2000, the fixing base 1000 is a separate component, the connecting base 2002 may be detachably connected to the lamp body 1701, or may be integrally connected to the lamp body 1701, and the second coupling portion in the connecting base 2002 may be integrated with the second body portion 2A, or the second electrical connection portion 2111 may be provided separately when the connecting base 2002 is integrally connected to the lamp body 1701. For example, the second coupling portion and the second electrical connection portion 2111 may be provided independently at different positions of the lamp body 1701 without providing the second body portion 2A.

The invention will be further elucidated by means of a specific installation example:

firstly, wires preset on a ceiling or a wall are respectively stripped, the stripping length is preferably 8-10 mm, then switch buttons corresponding to electrodes on the first main body part 1 are pressed, corresponding wires are respectively inserted, and then the first main body part 1 is screwed with the ceiling or the wall through a plurality of screw holes on the mounting support 2007, so that the first main body part 1 can be fixed on the ceiling or the ceiling.

Next, the connecting base 2002 is aligned with the center of the first body portion 1, and the connecting base 2002 is pushed up, so that the first conductive terminal 2061, the second conductive terminal 2062, and the third conductive terminal 2063 are received in the first receiving slot 41, the second receiving slot 42, and the third receiving slot 43, respectively.

Finally, the connecting seat 2002 is rotated to enable the protruding block 2003 of the first body part 1 to be installed from the opening end 2051 of the U-shaped installation groove 2005, and the protruding block rotates along the circumferential direction of the inner wall of the second accommodating cavity 2B until the protruding block is rotated to the position of the limiting structure 2052 of the U-shaped installation groove 2005, so that the protruding block is installed in place.

Because the protruding block 2003 is clamped in the U-shaped mounting groove 2005, and the axial acting force of the elastic element 2010 and the gravity of the lamp are added, the connection between the first main body part 1 and the connecting seat 2002 is more stable, and the mechanical connection of the lamp is realized.

Fig. 13 schematically shows a first body part 1 according to another embodiment of the present application. As shown in fig. 13, the first body 1 is provided with a mounting seat 2007 for connecting with a base such as a ceiling, and we refer to the contact surface of the first body 1 and the base as a top end surface, which may be a virtual plane and directly faces the bottom end surface 100A of the first body 1. It can be seen from fig. 13 that the mounting seat 2007 is located outside the upper end edge or the top end face of the first main body portion 1 in the present embodiment, the mounting seat 2007 is formed to extend outward along the upper end edge of the outer surface of the first main body portion 1, and the upper surface of the mounting seat 2007 is flush with the top end face of the first main body portion 1. Since the plurality of mount brackets 2007 may be connected to the base body by a connector such as a screw or may be integrally formed with the first body portion 1, and the mount brackets 2007 bear the weight of the entire lamp after the lamp is mounted, in the present embodiment, a first reinforcing plate 3061 is provided as the first reinforcing structure in the mount brackets 2007, and the first reinforcing plate 3061 is a substantially L-shaped sheet metal plate, and may be formed by punching or may be formed by bending the metal plate. The mounting support 2007 is provided with a mounting position capable of accommodating the first reinforcing plate 3061, when the first main body portion 1 and the base are connected, screws sequentially penetrate through the mounting support 2007 and the first reinforcing plate 3061 and then are fixed with the base, and therefore the first reinforcing plate 3061 in the mounting support 2007 can play a reinforcing role, the mounting support 2007 is prevented from being broken, and safety is improved. The mounting bracket 2007 is provided with a receiving space recessed along an upper surface thereof, in which the first reinforcement plate 3061 is received. The combination mode of the two can be assembly or coating molding.

In the present embodiment, the first coupling portion is a protrusion 2003 extending outward from the lower end edge of the outer surface of the first body portion 1, in the assembled state, the first coupling portion is subjected to a large external force, a second reinforcing plate 3062 is provided at the first coupling portion as a second reinforcing structure, the second reinforcing plate 3062 is also a metal plate, in the present embodiment, the second reinforcing plate 3062 is provided above and attached to the first coupling portion, and in other preferred embodiments, the second reinforcing plate 3062 may be inserted into the inside of the first coupling portion or integrally molded.

As described above, although the mounting bracket 2007 and the first combining portion become more reliable due to the reinforcement structure, the force of the lamp hanging on the first body portion 1 still needs to be transmitted to the base body through the first body portion 1, so we add the connecting plate 3063 between the first and second reinforcing

plates

3061 and 3062, and the two ends of the connecting plate 3063 are respectively connected with the first and second reinforcing

plates

3061 and 3062 to form a single reinforcement 3006, and the structural diagram of the reinforcement is shown in fig. 14. In this embodiment, since the first and

second reinforcement plates

3061 and 3062 are both metal plates, the reinforcement 3006 may be formed by bending a single metal sheet, or in other embodiments, the reinforcement 3006 may be made of other high-strength materials. Fig. 15 is a sectional view of the reinforcement member 3006 after being mounted in the first body portion 1, and in order to achieve the mounting of the reinforcement member 3006, the number of the first coupling portions and the number of the mount brackets 2007 should be the same, and the first coupling portions and the mount brackets 2007 face each other in the axial direction at the set position. For the connecting plate 3063, firstly, a through groove needs to be formed at the first main body portion 1 to accommodate the connecting plate 3063, and the connecting plate 3063 is inserted into the through groove, so that the outer portion of the mounting seat is smooth. In other preferred embodiments, the connecting plate 3063 may be attached to the outer surface of the first body portion 1 and connected to the first body portion 1 by a screw, a snap, or the like.

After the first body portion 1 is provided with the reinforcing member 3006, we also add a reinforcing structure into the connecting seat 2000, specifically referring to fig. 16, a reinforcing bracket 3206 is provided in the second body portion 2A of the connecting seat 2000, and a screw is inserted through the second body portion 2A and the reinforcing bracket 3206 of the connecting seat at the same time during installation. Reinforcing bracket 3206 may be provided on connecting seat 2000 or may be integrally formed with connecting seat 2000 by over-molding.

In addition, when adopting the lamps and lanterns of this application installation device installation lamps and lanterns, because first main part 1 and connecting seat 2000 realize connecting through the rotation, this is unfavorable for square lamps and lanterns, can make the lamps and lanterns frame can't keep the level with the wall and influence whole effect. Therefore, a positioning structure is arranged on the first main body part 1, the positioning structure comprises 4 positioning pieces which extend outwards from the first main body part 1, and the positioning pieces are uniformly distributed on the circumference which takes the rotating shaft of the connecting seat 2000 as the center of a circle. In this embodiment, we directly arrange 4 mounting brackets 2007 as positioning members, and the included angle between every two adjacent mounting brackets 2007 is 90 degrees. In other embodiments, the number of the mounting seats 2007 may not be 4, but in order to achieve positioning, there should be at least 4 mounting seats 2007, and when there are more than 4 mounting seats 2007, 4 of them may be selected as positioning members, and the mounting seats 2007 as the positioning structure may be distinguished from the other mounting seats 2007 in appearance (shape or color).

Next, we will describe specific steps of the lamp installation in this embodiment, where the lamp installation apparatus is used to install a square lamp:

the 4 mounting brackets 2007 provided in the first body 1 are fixed to the ceiling by screws, one wall is selected as a reference wall, and the line connecting the pair of mounting brackets 2007 provided is held perpendicular to or parallel to the reference wall. The external power supply line is connected to the first electrical connection portion.

The connection seat 2000 is previously provided on the lamp, the connection seat 2000 is installed in the first body portion 1, the connection seat 2000 is rotated clockwise, and the second coupling portion, i.e., the installation groove 2005, on the connection seat 2000 is also rotated to the first coupling portion, i.e., the bump 2003, and is hung on the bump 2003. The supporting state is kept to be downward slowly, the installation groove 2005 of the connecting seat 2000 is firmly assembled with the convex block 2003 of the first main body part 1 without loosening after the installation groove 2005 is confirmed to be effective, and the installation process is completed.

The mounting supports 2007 of the first body portion 1 serve as a positioning structure, a connecting line of a pair of the mounting supports 2007 arranged oppositely is perpendicular to the reference wall or parallel to the reference wall, and an included angle between every two adjacent mounting supports 2007 is 90 degrees. Since the number of the first coupling portions is 4 in total in accordance with the number of the mounting seats 2007, there are 4 coupling directions of the coupling socket 2000 and the first body portion 1, but the side wall of the square lamp can be kept parallel to the reference wall no matter from which of the 4 different directions the coupling socket 2000 is assembled with the first body portion 1.

In one embodiment, as shown in FIG. 1, a kidney-shaped aperture 111 is provided on each mounting bracket 2007. When the lamp is installed, the first body portion 1 is fixed to the ceiling through the mounting bracket 2007 and the waist-shaped hole 111. Preferably, the orientation directions of the four kidney-shaped apertures 111 are different, for example, the kidney-shaped apertures 111 on two adjacent mounting brackets 2007 are oriented radially, and the kidney-shaped apertures 111 on the other two adjacent mounting brackets 2007 are oriented circumferentially. Thus, when fixing the first body portion 1 to a ceiling, the two radially oriented kidney-shaped apertures 111 can be first fitted in place, in which case the first body portion 1 still has a certain adjustment margin; after the first body portion 1 is completely adjusted in position, the circumferentially oriented kidney-shaped apertures 111 are then fitted in position. Therefore, in the process of installing the lamp, a user can finely adjust the position of the first main body part 1, and the lamp is convenient to install. Of course, the circumferentially oriented waist-shaped holes 111 may be installed in place first, and then the radially oriented waist-shaped holes 111 may be installed in place, which has similar effects and will not be described again.

The present application also relates to a luminaire 1700. The luminaire 1700 has the first body portion 1 as described above and the luminaire mounting arrangement 2000 as described above. Furthermore, the method is simple. The lamp 1700 also has a lamp body 1701 mounted on the connection seat 2002 and electrically connected to the second electrical connection portion 2111.
